Removing just leading and trailing newline characters

Hi:

I am using FCKeditor in one of my form, when i copy and paste something
into it using WordPaste, it appends few newlines at the beginning and at
the end.
How can i strip just those \n without effecting the inbetween newlines
and the formatting.


TIA,
Priya

Re: Re: Removing just leading and trailing newline characters

Hi:

Its a simple form to create a job. FCKeditor has been placed with the 
name job[description].
At the create event, it assigns the value to @job.description.
I was trying to strip it before saving like:
@job.description = params[:job][:description].strip, but it isnt solving 
the purpose.

In the db, the description field shows a number of blank lines at the 
beginning and end.

No.  Strip removes all whitespace, not just newlines.
